The MOON 820S is
the large and eagerly anticipated
power supply that offers an upgrade
path for certain models. Making use of everything we
know about power supply design with
respect to circuit layout,
filtration and regulation has gone
into the 820S. Designed to elevate
the performance of products that
already perform stratospherically at
their price points, the 820S was
created through painstaking R&D,
creative ingenuity and a passion for
perfection.
Featuring state-of-the-art,
custom-built dual toroidal
transformers, choke filtering, and
our own MOON Reference Regulation
System (M-R2S) circuit, the 820S is
capable of doing what was once
thought of as virtually impossible:
improving on the already superlative
power supplies built into our
products, by further reducing the
noise floor while maintaining an
even greater voltage stability. The
astonishing sheer "blackness" of the
musical background created by the
addition of this power supply must
be heard to be believed.
The 820S is equipped with two sets
of outputs; It can upgrade the
performance of any one, or any
combination of two of the following
MOON products
simultaneously:
Each output
provides DC power for both analog
circuitry (audio) and digital
circuitry (controller, CD transport,
front panel displays) on 2 separate
and unique XLR type cables.
Technical
Features
-
Two custom
proprietary toroidal
transformers with lower magnetic,
electrical and thermal loss,
yielding an improved power
transfer and lower regulation
factor. The result is increased
current speed and better
dynamics; One each for analog
and digital power supplies.
-
Special "pi-type"
filters - 1 each for analog &
digital supplies - after the
inital voltage rectification
stage that reduce AC
transmission noise, using
40,000uF of capacitance and Dual
choke inductance (2x 20mH).
-
The analog
and digital supplies each have 4
stages of our M-R2S circuit; A
fully discrete voltage
regulation circuit using a "precision
reference" feeding an amplifier
comprised of numerous IC's and
transistors, as opposed to a
single voltage regulation chip.
M-R2S outputs pure DC power that
is exceptionally fast, very
precise, has a virtually
unmeasureable noise level, as
well as absolute stable voltage.
-
4-Layer
printed circuit boards with pure
copper tracings and extremely
low impedance characteristics
yielding much shorter signal
paths and drastically reduced
noise levels.
-
Ultra rigid
chassis construction to minimize
the effects of external
vibrations.
-
Accurate
matching of the very finest
quality electronic components in
a symmetrical circuit design.
-
Designed to
be powered up at all times for
optimal performance.
